This invention relates generally to the art of mattress making, andparticularly to a special form of mattress in which air-filled springconstructions are embodied into the filling.

The first object of this invention is to provide an exceedingly simpleand ecient mattress which will neither sag nor stretch.

The second object is to so construct the mattress that there will be amovement of air within the mattress whenever any of its portions arecompressed or released.

The third object is the utilization of air within the mattress as aninsulating medium which willmake this mattress warm in cool weather andcool in warm weather, owing to the fact that the air filler can absorband retain only a small amount of heat.

The fourth Object is the utilization of springs having initial tensionwhich are conlined within each biscuit of the mattress between pairs ofconvex covers, which covers also form the spacing means.

lThe fifth object is the centering of the springs in the variousbiscuits, and making it possible to employ roll edge and tuftingmachines such as are now in common use in the art.

The sixth object is to so construct our spring units that every portionof same will contribute to the resiliency of the mattress.

The seventh object is to combine the spring element with the means forlimiting the expansion of the springs.

yA'llhe eighth object is the provision of a frame around the assembledspring units Awhich will prevent their collapsing Vwhile beingintroduced into the mattress, and without whichsame could not beemployed with modern mattress making machinery.

The ninth object is to so construct the mattress and its component partsthat they will automatically adjust themselves to the contour of thebody, a condition which is essential to the ultimate success of anymattress.

These, and other objects7 will become more apparent from the followingspecification as illustratedin the accompanying drawing in which:

Figure 1 is a plan showing one corner of a completed mattress showingthe relation of the units thereto. Figure 2 is a plan of one of theunits showing the frame element which prevents collapsing of the unitswith relation to each other. Figure 3 is a side elevation of one of theyunits showing the outer frame members cut away in section. Figure l is avertical section through an outer biscuit showing the position of thespring unit in the mattress. Figure 5 shows, at a somewhat eX- aggeratedscale, the relation of the spring wires of a unit to a ring. Figure 6 isa view similar to Figure 5 showing the same relation when the springunit is compressed.

Similar members of reference refer to similar parts throughout theseveralfviews.

Referring in detail to the drawing, the in dividual spring unit consistsof a ring y10 which is octagonal in form and having lat tened areas 11between its straight sides for the purpose of forming hinged oints to,other rings by means of the clips 12 or for attaching same to a heavierouter frame 13 by means of the clips 14.

Above and below eachring 10 is placed a disk 15, each of which ispreferably provided with a central opening 16 and has hinged thereto thetwo pairs of bowy springs 17. One pair of bow springs 17 has its loop 18laround the ring 10 at one side of the clip 12,

and the other. pair of springs 17, which is integral therewith, has Vitsloop 18 around the ring 10 on the opposite side of the same cliplQ,which prevents rotation of the springs 17 with relation to the ring 10.

It will benoted that the junctions between the ends of the springs 17and the upper and lower disks 15 are in the form of a hinge, making itpossible for the unit to be flexed a great manytimes without any injuryto any portion thereof.

0f extremely great importance is the outer frame 13, without which it isnot possible to secure satisfactory results in the use of these units,since it is this frame which prevents their collapsing. while beingintroduced into the mattress or in subsequent use, and

Y the evidentimpossibility of restoring such collapsed units to theiroriginal extended position.

Earlier eidorts toward the use of these devices were almost abandoned asa failure until the frame 13 was evolved which held the units out totheir respective positions at all times, besides assisting in theintroduction of the assembled units into a mattress being fabricated.

ln Figures 5 and 6 it will be observed that while the bow springs 17 arenot compressed the ring 10 touches the outer side of the loop 18, andthat when the bow springs 17 are compressed (as shown in Figure 6) thatthe ring 10 touches the inner side of the loop 18. The former places thematerial in the bow springs 17 in tension and the latter places the samematerial in compression.

In Figure l it will be observed that the units themselves are coveredwith a suitable fabric 19 outside of which is placed the usual mattressfiller 2O which is confined within the usual ticking 21. Boll edges 22can be employed as in ordinary mattresses and the ordinary biscuits 23appear just as they do in the usual mattress construction, as do thetufting buttons 24.

V'llo all outward appearance the mattress appears very much as do othermattresses now in common use, but if one were to place his fist directlyupon one of the biscuits 23 and press downwardly thereon, whileobserving the surrounding portions of the mattress, he would find thatonly the portion of the mattress under his fist would move and thatthere would be no lateral movement of thesurrounding fabric, as isordinarily the case.

It will be understood that various means can be employed for fasteningthe various unit-s together or for fastening same to the outer frame 13.The particular construction best suiting the facilities of themanufacturer and other factors will, of course, be employed.

lt will be noted that the opening 16 in the disk 15 has an importantfunctionto per form in the manufacture of mattresses employing ourconstruction. After inserting the springs into the mattress the mattressmust be tufted and it is highlyimportant that each of the various springunits is in its correct position with relation to the tufts. rihe onedoing the tufting begins at a middle row of units and passes the tuftingneedle downwardly through the ticking and through the opening 16 of thenearest unit, and determines thereby the central location of the entiregroup of spring constructions7 since they are all tied together, andadditional rows of units must lie a fixed distance on one side or theother of the central row whose position is determined by the needle. Inother words,

all subsequent tuftings are made at fixed distances on each side of thebase line, or first row, thereby insuring that each and every tuft liesmid-way between four units, or, in the case of the outer rows of tufts,it lies between the outermost points of a pair of springs.

ive claim:

1. 1n a mattress spring, a hollow rectangular wire frame, a plurality ofrings secured to each other and to the frame so as to fill the frame,all of the rings lying in the plane of the frame, and a supportingmember resiliently held out of the plane of the frame centrally of eachring, one of the supperting means near the middle of the frame having acentral hole whereby when the sprin assembly is inserted in a mattressthe hoie in the ycentral supporting member can be iocated and used as abench mark or loeating point by means of which the tufting can bepoperly positioned.

2. 1n a mattress spring, a hollow rectangular wire frame, a plurality ofrings secured to each other and to the frame so as to fill the frame,all of the rings lying in the plane of the frame, and supporting membersresiliently held out ofthe plane of the frame on east side centrally ofeach rinff.

3. in a mattress spring, a hollow rectangular wire frame, a plurality ofrings secured to each other and to the frame so as to fill the frame,all of the rings lying in the plane of the frame, and pairs ofsupporting members resiliently held separated by spring means extendingat an acute angle from each ring to each pair, so that as the assemblyis pushed into a partially completed mattress it will present an acuteangled wedge formation with one of the sides of the wire frame at thepenetrating edge of the wedge.

t. in a spring unit to be joined to rows and files of similar units toform the central layer of a tufted mattress, a ring, a plurality ofbowed spring elements loosely joined to the ring and radially disposedwith respect to the axis of the ring, and a pair of annular anchors, oneon each side of the plane of the ring, connecting the ends of the springelements, the centers of the holes in the anchors lying in the aXis ofthe ring to serve as bench marks to facilitate the location of themattress tufts.

5. In a mattress spring, a plurality of springs, means for joining thesprings to form an unobstructed air chamber having the shape of asurface generated by an ellipse revolving about its minor diameter, saidmeans having a circular hole concentric with said minor dia-meter.

6. In a mattress spring, a plurality of springs, means for joining thesprings to form an unobstructed air chamber having the shape of asurface generated by an ellipse revolving about its minor diameter, saidmeans having a circular hole concentric with said minor diameter, and anoctagonal wire ring loosely associated with all of the springs to limitthe movement of said means from the ring.
